In this paper a state estimator for high tech flexible systems with an inherent nonlinearity in the output dynamics is proposed. We consider an application in which sensor measurements of the flexible system become parameter (position) dependent. An LPV setting is proposed for the design of estimators that estimate flexible modes of the system. The possibility of pole placement for the error dynamics...
This paper focuses on observer design for a flexible motion system with a state dependent output map. After rewriting the modal system to parameter varying form sufficient conditions are derived to obtain a parameter varying modal observer with bounded ℒ2 gain. These conditions translate to linear matrix inequalities (LMIs) when the time derivative of the Lyapunov function is multiconvex. The derived...
